Mobil 254 vs Mobil Jet II

What is the difference between Mobil 254 vs Mobil Jet II? And can you run either in a Jetranger engine?

Thanks a lot in advance for any info on this!

I’m no LAME, but I’m of the understanding is that Jet 254 is a better oil that prevents carbon build up, whereas Jet II doesn’t.

If you are running Jet II, you can’t switch to 254 as it will release the carbon and potentially block the jets.

Both are suitable for the Jetranger. The Jet II has more of an orange tinge to it.

Do not mix Oils?

You can switch from running Jet II to 254, however you have to do it at the overhaul of the component.

I guess everything should be clean going back into the helicopter and you are starting almost new.
